` To all whom it' may concern:

v-Be it known that I, PETER SoLAiNi, a citizen of Italy, and residing at New York, in

the county of New York and State of New invented f new and useful Imroveinents -ini vEmbroidery Devices, of

which the following is a specication.

.Theobjectv of my invention is the production of a simple, practical and inexpensive device for .embroidering or working raised designs in thread upo'na fabric.

The invention consists in' general of a holder within which there is mounted a reciprocating needle carrier and a special feature of the invention resides in the provision of a tensioning device which operates as the needle iswithdrawn from the fabric to draw onone-,side of the loop of thread which the needle has just previously carried through tion ofA the loops vthus Y to. clamp the thread or thevfabric. This renders the loop-forming action of the needle uniform and even. For the purpose of varying the size or formaproduced b'y the needle, the invention contemplate's'the provision of means for varying the stroke of the .needle carrier and hence of the needle. After working in a desired design or figure upon the fabric the loops Vare usually clipped so as to leave the design appearing raised or upstanding upon the face of the fabric. l

.The tensioning device is usually in the form of a thread-engaging element slidably mounted on the needle carrier and arranged yarn against a shoulder on the carrier. lThe 'needle carrier is reciprocated by a suitable handle and this handle is preferably connected with the slidable tensioning element so as to operate it in time with the movement of the needle.

A special feature consists in adjusting the connection between the operating handle and tensioning elementto vary the tension eX- erted upon the thread.

A further special feature of the invention consists in mounting the needle in the needle carrier so that it can yield laterally to a certain extent. The effect of this is to cause the needle to step forward each time it is withdrawn from the fabric'and so produce an automatic and natural feeding action of the device over the fabric. This yieldable characteristic also prevents the needle from be- .ing broken by accidental sidewise pushing on, the device.

" a fabric and illustrating is shown in the T having a foot 8 to bear upon the fabric.

rious changes and modifications may be madewithout departing fromthe true scope and spirit of the invention.

Figure 1, is a perspective view of an enibodiment vof the invention. Fig. 2,is a drop perspective view showing the several parts of the device. Fig. 3, is a vertical sectional view of the device as in use, showing the needle just withdrawn from the fabric and stepped forward ready to make the next down stroke. Fig. 4, is a broken view show ing the lower portion of the device, with the needle just completing its downward stroke.A Fig. 5, is a similar view with the needlev just 4about completing its upward stroke. Fig. 6, is a perspective view showing a flower design partially worked upon the appearance of the pile-forming loops both before and after being trimmed or clipped.

The body or holder portion of the device forin of a tubular member The needle carrier is shown as a hollow cylindrical member 9 slidably engaged in the holder so as to reciprocate therein.

10 designatesV the needle mounted in the lower end of the needle carrier. This may be an ordinary sewing machine needle.

The needle carrier is usually guided and held :against turning in the holder by p roviding it with a lug 1l working in a `guide slot 12 in the holder. The lug 11 may be perforated as shown, to form a thread guide. The upward stroke of the needle carrier is limited, in the illustration by an outstanding lug 14 on the lower end of the tubular holder (see Fig. 3.) The down-stroke of the carrier and hence the active stroke of the needle is governed in the case shown by an annular abutment l5 adjustably engaged on 16 of the carrier and designed to engage the top of the holder..

suitable handle 2O and this handle is, in the x ,A present case, utilized also to operate the tenthe screw-threaded shank portion.

This annular abutment is internally threaded toiit the screw threads r The needle carrier sion device. neeting the handle direct with themovable elementv of the tension device.

In the form of tension device illustrated in the present disclosure there is a movable thread-supporting element A2llasl'idably mounted inside the tubular bod of the needle carrier and. this member *is hooked at its lower end to provide spaced substantially tween them a thread This abutment is shown in the form yof a through' which the clamp memberis passed sb as to be guided thereby. The handle 20 is mounted direct upon the upper erld of the movable clamp member, it being, as indicated in Fig. 3, adjustably secured thereon by means of a'nut 24, engaged on the threaded'end portion 25 of'said member.

The reciprocating tension clamp guided at its upper end by working through a guide opening 27 formedl which. is secured on the upper end of the needle carrien The .down stroke of the clamp member is determined bythe handle coming into engagement with the top of the cap. This will be clear from Fig. 8. The up stroke of the clamp is limited by the thread pocket on the lower end thereof engagingy with the relatively fixed abutment loo as also appears in Fig. 3.

rlphe .thread or yarn, indicated vat 30 is guided across the thread pocket by being passed' through guide openings 3l, in the parallel sides 22 of the clamp member. The

section of thread lying in the pocket is thus always in position to be clamped against the relatively stationary guide loop. is preferably held against too free sliding movement`V in the holder by frictional retarding means such as the bowed spring 33 ing against the inner wall of ,the holder.

In the construction illustrated, the needle is allowed to a certain lateral yielding action by fastening it in a chuck ir the form of a socketed block 35 which is pivoted at 86 in the lower end of the needle carrier. The needle' is removably and adjustably held in the socketof the chuck by a clamp screw 37. The needle chuck is held normally with the needle in a forwardly tilted position (Figs. 1 and 3) by a spring 38 bearing upon the upper' forward corner of the chuck, as shown in Fig. 3.- t

In operation, the holder portion of the device/is held in one han.1 with the foot of the device pressed firmly upon the stretched cloth or fabric 40. WVith the other hand the handle 20 is grasped and a reciprocating movement is imparted to the .needle carrier. Upon the downstroke of the needle carrier the needle carriesa long loop 41 of thread parallel side portions 22 forming be! pocket to carry thc. thread in clamped enga-gement with a rela!-v tively fixed abutment.

down through the fabric (Fig. 4). During this downstroke the thread-tensioning device releases its grip on the thread (Fig. 4) vand the thread is therefore freeftois'lide through the needle to furnish a ll the thread needed forthe full loop. of the needle carrier, the upward pull on the handle first lifts the movable clamp clement into thread-gripping position and as the hooked lowerend of the clamp engages with the guide loop 23, a positive connection yis 'afforded between `the handle and needle carrier and the needle carrier `then nieves with 'the handle. During this z pward 1etracting movement of'thc nciwllttherefore, the'tln'ead forming one side of lle loop just produced by the needle is gripped in the so that as it penetrates the fabricon its' 1 and 2) it serves to draw forward a distance apto its inclination. Upon downstroke (Figs. the device bodily proximately equal On the up stroke the upstroke,vthe pivotal mounting permits the needle to straighten out (Fig. 5) and then as the tip of the needle clears the fabric the spri'ng throws the needle forward to its original inclined position yso that it` infefl'ect automatically steps out and therefore. on its next stroke enters the fabric at a point in advanceA of the lastformed loop (Fig. 3).

'lhesize ofthe loops formed on the underside of the fabric 'can be varied by changing the stroke of the needle carrier through the medium of the adjustable abutment '15. A further variation is obtainable by varying the stroke of the tension device through the medium' of the adjusting nut 24.

Fig. 6 shows a piece of fabric whereon there is markedv a flower design 50 one of the petals 51 of which has been worked in with the loops forming an upstandi'ng pile fabric and Ytwo other petals 52 which have pearance of 4a flower resting upon the sur ace of the fabric.

In addition to providing for formation of i different-sized loops the adjustments of thel needle carrier and tension device providev the thread different degrees of tension on and allow for the use of different kinds and feeding action renders it necessar to guide the device in the What I 4claim is 1.
